A Dutch SME has patented a process of production of a base material for ASC cement, which can fully substitute Portland Cement ( O.P.C. ). The base material ( ASCEM slag and filler ) has special properties ( with respect to O.P.C. ) and can be used as a component in cement. The technology is broadly applicable in mortar and concrete products and structures. The company is looking for collaboration with companies for a license agreement, or a commercial agreement with technical assistance.
